F 7 The correct cutting speed is indicated by the type of chipping you obtain during the cut: thin and/or broken means that the cutting pressure is insufficient: increase progress. thick and compressed, with bluish colour means excessive force: reduce progress/speed. Thin and wound in spirals: indicate correct use of the cutting parameters.
